Got it thank you so much its homing now. And its just the mesh levelling that I need to sort out. Seems it probes a few points then says that that the probe was activated at the next point already.

all jogs right now from what I can see. Just z does not home when homing all axis now

M569 P0 S1 ; Drive 0 goes forwards
M569 P1 S0 ; Drive 1 goes forwards

Sorry my english is failing me today I meant I had to do this after I swapped the drivers around. Now just that screeching noise and to get Z to actually home

Sorted had to change the second line to S1. Now when I home after it hits the endstops there is a screeching noise.

Hi

So I have been trying to figure out how to change the X home direction but alas I am failing. This all started with trying to get the axis actually moving in the right planes. Y moves home in the direction I want now etc but X still gives me hassles as it wants to home to the + side. How can I set this in firmware? I believe the 569 setting needs to be changed however if I change this it just makes everything go in diagonals. i have also tried switching the between the drivers but I still end up in the same place. config as follows:

Right so the ones I had were an utter fail and didnt work. So I am getting the right ones. Just to confirm I need to get either one of the following :

http://za.rs-online.com/web/p/rectifier-schottky-diodes/1038145/

Yes that's correct.

Thanks so much will be getting them then

Cool will do tonight thanks so much. Its my first duet so dont want to mess it up

@whosrdaddy:

Use a small-signal Schottky diode such as BAT43 or BAT85

I get that but my question was more around whether the diode I linked to would work for the application as I have them in bucket loads

@dc42:

I suggest the same wiring as for an NPN inductive Z probe, see https://duet3d.com/wiki/Connecting_a_Z_probe#NPN_output_normally-open_inductive_or_capacitive_sensor. However, as your endstops can work on 5V, it should be safe to power them from 5V and connect the output directly to the endstop input without the diode.

Hi based on that article would this work? https://za.rs-online.com/mobile/p/rectifier-schottky-diodes/7044013/

Anybody?
